To a]! "whom it 7mm con/corn:

Be it known that l, Jonu ll. ELFERiNo, a. citizen of the U nited cilntos, residing it Cinnden, in the county of Camden and State of New Jersey, have im'entcd certain new and usorul improvements in 'izillringiliochinos,

of which the followinp n specification.

My improvement is applicable especially to disk talking nmchincs, and tllO'ObjBGt of my invcni'ion is to provide means for presenting the rsprm'lucing sound box to the record in the most advantageous position for tho production of sound, mid the prescrvzition of the record and noodle. The munner in which I utiinin thcsc objects is illustrated in the accompanying drawings, in which 1- Figure l is n sidc View of the mo xhunism attached to u unichinc. Fig. 2 u. sidc vicw oi the some separate from inc machine, and, Fig. 3, 2i plan showing: lhc movcmcnt accomplishcd by he nuw-flmuism.

biimihu' lot 'Lers rcicr lo similar ports in iho scvcrz-il views. 1

To the cabinet Ii is secured tho cnglc piece B, i. c projecting port of which is adopted to hold the domiwzu'dly cxtcudin g pin (1. To tho angle piece B is securod the block 1). The arm 2* is iittcd. with two pointcdscrcws i nndf, and isihcroln'pivoted upon the block l). Ncur rho otlu r end of tho arm i i nnothcr pointcd screw (l: is located. The upwardly cxionding purl of lhc u-rm E, is provided with :1 ring i l which is liitcd with the tube ll, hold in plaice bx tho sot .scrcw 1. Resting" upon tho pointed scrcw C, and having tho upper cud pivot ally supported in place by the iubo ii is lhc hub}. 'io ihc hub J i scoured inc arm ii, to the projeoi' nd oi which is smu -ii lilo doxvnw'w'dly 1 ncndin pin ll. ihc ccrdrzil pm'lion'ci irho arm ii hv lhe screw El is lhc levcr i\ siotlcd luv coco cud, lo loosely engage ihc pins and ii.

Attached to (he hub J is liho Lube i), sup

porting'niits cnd the sound box P, i ho nordlo point being shown all bl. Tho tube 0 is in two ports, ll extending port bcing pivoted upon the part attached to the hub ll by U10 pm i 'lhc tube ll is also adopted lb servo as i h support for the small cnd oi the amplifying horn h. A further support for 1110 born 5 is the rod 'i screwed u; the firm confer in: means oi; the

ubovc i screiwf. and fitted. with a bent wire U upon which the horn rests. supporting the turn table, upon which is placed the record V.

'lhc ope ution of the devices described is as follows z--The tube 0, pivoted at Y, al lows the nccdle R to rest noon and inthe spiral groove ofthe record being revolved by the motor of the machine, the needle pointis continually being moved toward the center of the record a distance equal to one groove for each revolution. This movement of the needle turns the attached hub J upon the pivots, screw G and tubell, and causes tho pin L, inthe'attoichcd arm ii to engage with the slotted arm N, moving tho end engaged with the pin L in the sumo direction the arm K tube 0 and sound box needle R. Tho other end of. lo vcr N cngagcs with the pin (1, and is held at its fixed point but for the slight end movemcnl', the slot compensates for. There is therefore a. relative movement csmb'lished by the lover N betwccn the arm E and arm U, so that the arm 0 and clinched sound box 3 maintain a position parallel with the line e--aa throughout the course of movemenfi'; tho noodle at the sonic time moving in tho :nc ol ii circle b b, of which the distance from the pivot screw f to the pivotscrew G is the radius. The spiral grooves in the record J being approxinmtely tangent to the A spindle Vi is shown.

The record line (k -(UL at the point of contact with the nccdlc, the sound box is hold tangent to them and the needle in u fixed rclzitivo position throughout the movement. The amplifying horn S incnscs at one cud the iubc ii for the rccoption of the sound, and is supporicdby the rod. '1 above the center oi? tho pivot screws l1, j, to minimize tho i' cndcncy n) prevent the easy movement of rho mecluniism. A passage for the sound into the horn :3 is provided by the chamber oi tho Lube liollov. hub J and tube H.

'lypes ol'- talking nmchinos employing the sound box 1 attachml to the tube 0, ivoted upon tho pin '1" iixcd in tho. part of 1; 1e tube iit'mched to a hub similar to hub J, pivoted between pivot screw Cr and tube H the screw G and tube ll being attached to an arm rigidly held by the cabinet, thereby allowing i-hc noodle ii which the pivot (1: would be the center, have boon mode. 1. do not claim these devices in the record surface and means for maintaining the stylus substantially tangent with the record groove.

2.
